Cutting liner lock liners

[happycat]

I am working on my first folder (a liner lock) and I have all the pieces cut out and roughly assembled. Here is my question.

How do you cut the cut the slot down the middle of the liner to form the lock. I have mine planned with a compound angle on the end which meets the end of the blade so it has two faces of the blade to lock against. I am just at a loss of how to go about cutting this thing.

The most obvious option I can see is to go and buy or borrow a jewler's saw with a very fne blade and cut it out by hand. I also have a fordam tool and I suppose I could grind it out with that but that seems pretty messy.
Any suggestions?

Happycat- I have made one liner-lock , my good friend Dale Reif helped me with it . It has Titanium liners I used a Dreml tool with a grinding wheel "stone" not the fiber cutoff wheel to make the slot for the lock it took about 20 min. and it splatered grit and white hot sparks but it worked . If you are using titanium I think the Fordom you have would be better.

the cleanest way to do it is put it in a compound vise/put your foredom tool in some kind of fixture so it doesnt move..you could clamp it to your drill press quill.....and slowly feed the cutoff wheel into the ti... ti is tough stuff...and if your cutting tool and your liner are not firmly clamped down, like you said...it will be a mess....maybe you could go over to someones and con them into doing it on their mill....i will volunteer...haha....make sure to leave the lock just a smiggen long so you can cut it back to fit the angle on your blade...and the compound angle part sounds like a BAD idea to me.

Toms right, that compound angle would be a bear to fit to the tang. I first use my
band saw to cut the portion that will become the lock. I cut it about .020 longer than
needed, so I can file to fit. I then use a foredom (Wear Eye Protection!!!) and a cutoff wheel, to cut about 1/3 of the slot. With my band saw turned *OFF*, I put the liner in and cut the rest of the slot. I'm not sure how to explain that, but it does work.
